尽管编译了库的通用版本和 i386 版本，但未找到体系结构 i386 的符号
Symbol(s) not found for architecture i386 despite compiling universal and i386 versions of library
我一直在用C++开发一个动态库，在xcode命令行界面项目和gtest项目中测试时编译运行。
然而，当我尝试在 openframeworks 项目中 link 它时，linker 抱怨无法为我的 [=51= 之一的某些功能找到 i386 符号]是的。这特别奇怪，因为它可以看到 21 个函数、构造函数和析构函数中的 16 个的符号……我知道这一点是因为我可以调用所有 16 个函数而不会出现任何 linker 问题并获得预期结果。
这是 Xcode 吐出的内容：

我知道 64 位功能仅在版本 9 中出现在 openframeworks 中，因此编译为通用二进制文件。我什至尝试过专门为 i386 编译，但没有成功...
我已经为 openframeworks 项目尝试了各种架构和 SDK，但除默认 $(NATIVE_ARCH) 之外的任何其他架构和 SDK 都会阻止 openframeworks 本身编译。库搜索路径指向正确的位置，我 link 在构建阶段指向正确的库，这很明显，当对有问题的函数的调用被注释掉时，它可以愉快地编译和运行。
我有一种挥之不去的感觉，这是一个 C++11 问题，因为它在我的整个库中使用，如果我没记错的话，openframeworks 在 C 方面有问题++11。如果有人认为它可能是其他东西，我将不胜感激！！！

事实证明 Openframeworks 不喜欢 C++11 二进制文件...我通过不对相关应用程序使用开放框架来解决此问题。
我一直在用C++开发一个动态库，在xcode命令行界面项目和gtest项目中测试时编译运行。
然而，当我尝试在 openframeworks 项目中 link 它时，linker 抱怨无法为我的 [=51= 之一的某些功能找到 i386 符号]是的。这特别奇怪，因为它可以看到 21 个函数、构造函数和析构函数中的 16 个的符号……我知道这一点是因为我可以调用所有 16 个函数而不会出现任何 linker 问题并获得预期结果。
这是 Xcode 吐出的内容：
